Thank you. Just found this thread too which was a big help in understanding the shutter speed range in ms vs the fractional shutter speed that I am used to seeing.
So left in auto, it seems the shutter speed is so slow at night that any cars driving past is a streak, can't even tell the make/model or SUV vs Sedan.
I'm using 2 starlight lite cameras 0.007/0.008 lux The street light is actually sufficient to get the camera to run in color mode up to 1/250 or 1/500 if I force them in manual mode but even 1/500 shutter is too slow (over exposed) during the day.
1) anyway to set a shutter "floor" so that it can have a faster shutter during the day but will not go slower than a pre-defined shutter speed at night by auto-adjusting gain instead?
2) anyway...
